create an empty directory, e.g. mkdir test
create empty directory mkdir test/cmake
create empty file touch test/CMakeLists.txt
run: qtcreator test/CMakeLists.txt
Click next or select different directory.
The cmake result textbox will be empty and nothing will happen at all.
Maybe somebody tries to execute a directory here?
You can also exchange the cmake directory by a script, which then will be executed.
(This might be the desired behavior, but the directory case is strange.)
In our configuration the PATH env variable contains the current directory '.'.
